As electricity flows through a copper wire, the temperature of the wire increases. Some parts of the wire get warmer than others, but over time the wire is the same temperature from end to end. What kind of heat transfer takes place to make the wire a uniform temperature?

Conduction

Explanation:

The heat can be transferred in the substances in three ways: conduction, convection, and radiation.

The conduction happens inside the material, usually a solid, and the heat flows as the molecules of the substance are agitated. The convection happens when there are different substances in touch, so it is the heat passage from a solid to a liquid or gas, from a gas to a liquid or vice versa. The radiation occurs between substances that are far away and the heat flows by electromagnetic waves.

Thus, in the wire, the heat flows by conduction.
